Application filed January 1909. Serial No. jd.

into a car purified air. i.

A furtherobject of my invention is to provi`de a ventilator adapted tocontain a quantity of water or liquid to saturate an endless porous orfabric belt arranged in the ventilator to separate the air inlet fromthe air discharge, so that gaseous odorsfrom the inlet ma be caught orarrested by the belt to obviate the entrance of said gaseous odors andwill be .excluded from the car, said belt as before stated also servingto arrest all foreign matter.

vd still further object of my invention is to provide hollow rollers forthe endless belt, a trough or water receptacle for :moistening the belt,and to further provide means for heating the rollers to prevent, in coldweather freezing of the belt or the water in the trough, thus eecting atall times a perfect operation.

Other objects and advantages will be apparent as the nature of theinvention is better set forth, and it will be understood that changeswithin the scope of the claims may be resorted to without departing fromthe spirit of the invention.

ln the drawings, forming a portion of this specification and in whichlike numerals of reference indicate similar parts in the lator beingshown in section.

several views Figure 1 is a diagrammatic view showing a carhaving myimproved ventilator applied thereto, parts of the venti- Fig. 2 is anenlarged vertical section through the ventilator. Fig. 3 is a side viewlooking toward the side of the ventilator. Fig. f1 is a detaillongitudinal section through a portion of the ventilator.

Referring newr more particularly to the drawings, there is shown indiagram in Fig. 1 a car A which is provided with a bracket Bforsupporting an axle C upon which is vmounted a pulley D. One axle E ofthev car A. carries a pulley F, and this vpulle and the pulley D receivean endless belt The axle C is also provided with a pulley H for apurpose to be hereinafter more fully described. When the car A is inmotion,V

it is obvious that power derived by the axle E will be utilized to drivethe axle C.

The ventilator is shown at 1 and comprises an elongated hollow bodhaving an upper portion 2 which is' pre erably constructed of Wood orthe like and a lower portion 3 which I preferably construct of copper,but1 as will be readily appreciated I do desire to limltniyself to thesole use of copper but desire the privilege to use any such` metal thatwill atord a water roof structure.v The port-ion 2 of the ventilator 'isprovided upon the outer side thereof with an opening f1 in its sidewall, and this opening is covered with foraminous material 5. Theopening 4 will be hereinafter referred to as an inlet, and the innerwall of the portion 2 is provided with what may be termed a dischargeopening 6 arranged to be closed by a hinged doo'r 7.

The end Walls 8 of the ventilator have formed therein adjacent to theirlower ends alining passages 9 which receive the hollow journal members10 at the ends of a hollow roller 11. The hollow journals 10 are passedthrough suitable stuiiing boxes 12 at the ends of the ventilator asclearly shown inl-Fig. 4 of the drawings. @ne of the hollow journals 10carries a pulley 13, and connected with this ulley, and with the pulleyH upon the axle (l) is a belt le.' A roller 15 of hollow form is locatedadjacent to the upper end of the ventilator and is also provided withhollow journals 16 at the ends thereof revolubly mounted in bearings 17.A steam pipe 18 is passed through the roller 11 and a similar steam pipe19 is passed through the roller 15. At one end, thesteam pipes 18 and 19are connected by a pipe 20. At the other end the pipe 13 is connectedtoa pipe 21 which receives steam or heating fluid from' the heatingapparatus of a car. From the construction just described it is obviousthat the steam or other heating fluid can be effectively carried fromthe pipe 21 through the pipe 18 to heat the roller 11, and the steam orheating fluid will also be carried from the pipe 20 into the pipe 19 toheat the 'roller 15, and from the pipe 19 the steam or duid may bedischarged from a pipe 22.

A belt 23 is passed over the rollers 11 and tudinally extending troughor receptacle 24 in which is disposed a portion of the roller l asclearly shown in Fig. 2 of the `drawings. The trough 24 receives at itsbottom the upper ends of drain and flushing pipes 25 which are providedfor flushing the trough or for entirely draining the same of water. Theportion 3 of the ventilator is provided at a point above the bottomthereof with a plurality of overflow pipes 26 so that, incident to themovements or vibrations of the car should water escape from the troughit willA be discharged from the overflow pipes 26.

By providing the stuiing boxes 12 toreceive the journals 10 ofthe'roller 1l, it is obvious that it is impossible for water should itbe discharged from the trough to leak l operation of the downwardly fromthe sides of the ventilator. Upon the under side of the Jtop of the por-`tion 2, I secure alongitudinally disposed strip of felt 27 to preventthe entrance of foreign matter into the opening 6.

In operation, when the car is in motion, power will be supplied to theaxle C to revolve the roller 11 to operate the belt 23 so that it willbe elfectivelysaturated at all times in view of the fact that'a portionof the roller 11 is disposed in the trough 24. As hereinbefore statedheat is passed through the pipes 18 and 19 so that the rollers 11 and 15are kept warm at all times to prevent freezing of the belt and the-waterin the trough belt at all times.

By constructing a ventilator as described in the foregoing, it will beunderstood that should silt, cinders or any other foreign matter enterthe ventilator through the oraminous material 5, such matter will beconfined 24, thus providing a perfect at oneside of the belt 23 andeffectively held against entering the other side of the ventilator toavoid its passing by wayv of the passage 6 into the car. B, saturatingthe belt 23 and by arranging tfie belt so that it divides the ventilatoras shown in Fig. 2 of 'the drawings into what -may be termed an inletcompartment 4a and what may be termed a discharge compartment 4b so thatair in entering the ventilator will pass through the belt 23 to becomeiltered and to separate the air from the gases, so that the compartment4b can at all times contain a quantity of fresh air to be dischargedinto the car by way of the passage 6.

I claim:

In a ventilator, the combination with a receptacle having a foraminousportion at one side and formed at the other side to provide an opening,a closure for the opening, the said receptacle being formed to provide asubstantially trough-like bottom, a water feed connection openingdirectly into the said trough-like bottom, of superimposed hollowrollers extending the entire length of the receptacle, the lower rollerhaving a portion extending int-o the trough portion of the bottom of thereceptacle to be partly submerged in the liquid therein, a fabric. beltextending over ing arranged immediately between the opening and theforaminous portion respectively of the said receptacle and dividing thereceptacle into separate compartments, heating elements extendingthrough the rollers, and driving mechanism geared to one of the rollersand operating to continuously revolve the belt and to cause the same-tobe saturated by the liquid in the trough-like bottom of the receptacle.

In testimony whereof I affix my signature in presence of two witnesses.ROBERT W. MARTIN.
